YMCA Rockies Wind River
Modelled boundary. EPA estimated this service area (Random Forest) rather than tracing a utility-supplied map; treat the edge as approximate. About 5 km².
Where the water comes from
| Facility | Kind | Water |
|---|---|---|
| PURCHASED WATER FROM ESTES PARK | Non-piped, purchased | Surface water · from ESTES PARK TOWN OF |
These are EPA's facility records, not DWR structures. Which decreed rights sit behind an intake is the next phase; nothing here is inferred.

DWR structures that name this system
Source Probable join · fetched 2026-09-09 · matched on DWR's recorded contact or an EPA intake name; verify on the dossier
No DWR structure on file records this system as its contact, and none of its EPA intakes matches a structure name in its districts. DWR records a contact on only a fraction of structures, and only for districts fetched from its live service, so this is absence of a record, not evidence of no rights.
Compliance record
Source Register of another agency · fetched 2026-09-09 · verify at EPA ECHO ↗
2 violations open now, none health-based. These are monitoring, reporting or notice requirements — a sample not taken, or a result not filed on time. They are real obligations, but they are not a finding about the water itself.
EPA's own summary: violations in 12 of the last 12 quarters, significant non-compliance in 2. In violation for, in EPA's words: 0200=Surface Water Treatment Rule; 0999=Chlorine; 2456=Total Haloacetic Acids (HAA5); 2950=TTHM; 5000=Lead and Copper Rule; 7500=Public Notice. Currently: 5000=Lead and Copper Rule; 7500=Public Notice.

What the regulator did about it
218 enforcement actions on this system's federal record. In Colorado the state is the primacy agency, so most actions are the state's; EPA acts directly on tribal systems and when it steps in.

Lead and copper
The latest 90th-percentile lead result is 0.002 mg/L (sampling period ending 2026-06-30) against an action level of 0.015 mg/L, below it. 13 results on file.
The action level is not a health limit: it is the level at which the rule requires a system to act (corrosion control, public education, and in some cases replacing lead service lines). Lead mostly enters water from household plumbing, so a system-wide percentile does not tell you what comes out of one tap.
Violation, enforcement and lead/copper records are EPA SDWIS federal reporting, fetched monthly; the summary is EPA ECHO. Code names come from EPA's own REF_CODE_VALUE table. SDWIS carries violations, not routine sample results — nitrate, disinfection by-product and PFAS values are not in it, and a clean record here means nothing was reported as a violation, not that nothing was ever detected. For what was measured, ask the system for its Consumer Confidence Report.
PFAS and lithium: EPA's UCMR 5 monitoring, 2023–2025

5 samples, 120 results, 2024-07-15 to 2025-08-12. No PFAS was detected at the reporting limits; lithium was not detected.
| Contaminant | Results | Detected | Highest, µg/L | Reporting limit |
|---|---|---|---|---|
| HFPO-DA | 4 | 0 | < 0.005 | 0.005 |
| PFHxS | 4 | 0 | < 0.003 | 0.003 |
| PFNA | 4 | 0 | < 0.004 | 0.004 |
| PFOA | 4 | 0 | < 0.004 | 0.004 |
| PFOS | 4 | 0 | < 0.004 | 0.004 |
| lithium | 4 | 0 | < 9.0 | 9.0 |
Rows shown: every detected contaminant plus the regulated PFAS and lithium; the rest were below their reporting limits. These are UCMR monitoring samples, not compliance samples. EPA's April 2024 rule set 4.0 ng/L (0.004 µg/L) for PFOA and PFOS, the same as UCMR 5's reporting limit, so any detection of either is at or above it; the rule's compliance date and its other limits have been under revision since 2025 and are not applied here. State PFAS sampling is on CDPHE's pages ↗.
